The GS610 is a highly accurate, functional, programmable voltage/current source that incorporates both voltage and current generation and measurement functions. The maximum output voltage and current are 110 V and 3.2 A, respectively. It enables the evaluation of a wide range of basic electrical characteristics because the GS610 can operate as both a current source and a current sink.

The GS820 Multi-Channel Source Measure Unit comes in 18 V and 50 V models for LED lighting testing, drain current measurement, and more. It features two isolated analog channels, each equipped with a constant voltage source, constant current source, voltmeter, and ammeter. The Yokogawa GS820 source measure unit offers two sweep functions, PC connectivity via USB, and expansion up to 10 channels.

The INCON® 1511-LTC provides basic LTC tap position monitoring using the LTC’s slide wire position feedback device. As the LTC changes taps, the moveable contact picks up the voltage divided through the resistors in the slide wire, so that each tap has its own specific voltage.

The INCON® 1250-LTC Programmable Load Tap Changer (LTC) Position Monitor relays critical position information between a distribution transformer LTC and the LTC controller, enabling utilities to run their transformers as efficiently as possible.

The INCON® 1250B is a versatile programmable position monitor. Its main application is for Transformer LTC position monitoring, but its non-linear conversion table gives it the ability to convert non-linear rotary motion into a linear scale for additional applications.

Built upon Yokogawa's history of developing superior sourcing instruments, the LS3300 is an AC signal generator capable of simultaneously outputting current and voltage, thereby enabling the calibration of power measurement devices such as clamp meters/current transformers, panel meters, RMS multimeters, and power meters. The LS3300 delivers up to 78.5 kW per unit, with user-configurable settings for current, voltage, frequency, and phase. New features include a high-definition LCD display, a vector diagram, and the ability to synchronize up to three units to emulate everything from single-phase 2-wire to three-phase 4-wire systems.

The INCON® Optimizer3 Circuit Breaker Monitor delivers advanced automated reporting of all critical circuit breaker diagnostics to ensure uptime and facilitate predictive maintenance. The Optimizer3 is ideal for high-voltage, live or dead-tank, oil, vacuum or gas circuit breakers.

The INCON® Distribution Transformer Monitor (DTM) provides continuous, meter-grade precision performance monitoring of high-value, mission critical, low voltage pad mount and conventional pole mount transformers.

The CELLGUARD™ Wireless Battery Monitoring System (BMS) provides an accurate and reliable indication of battery state-of-health through monitoring and analysis of battery voltage, temperature, and conductance. 

Yokogawa's Power Analyzer software manages numeric, waveform, and harmonic data measurements. It enables data logging and instrument configuration from your computer.

CELLTRAQ™ Enterprise (server-based) and CELLTRAQ™ Express (PC-based) allow users to manage battery system data generated by maintenance routines using CELLTRON™ Battery Testers or CELLGUARD™ Battery Monitoring Systems.

Precision voltage probes for demanding measurement applications. Voltage probes are the critical interface between the circuit under test and the oscilloscope, preserving signal integrity, providing isolation, and matching measurement needs—from high-speed signals to high-voltage power systems. Without the right probe, even the best oscilloscope can produce misleading results. Yokogawa voltage probes are engineered for both general and specialized measurements, delivering exceptional accuracy, signal fidelity, and safety. Whether capturing fast transients, analyzing waveform integrity, or isolating differential signals, Yokogawa probes are designed to complement the performance of their industry-leading oscilloscopes.
